Good Product at a Great Price
Ordered and received correct part. Came in just two days with free shipping. Tool worked great. Was about half price of same part at other local auto parts stores.

Oxygen Sensor with Install Tool.
I have no complaints with this order. Everything matched and worked perfectly. This was a "downstream" Oxy Sensor that I ordered and the install tool was for the "upstream" sensor. No room to use it for this application. I just used an open end wrench to remove and replace the sensor. No problem. Would buy from 1A AUTO again.
